问题描述
我想通过像这样给它较小的 y 和 x 变化来减慢圆圈的运动:
I wanted to slow down the movement of the circle by giving it smaller y and x change like this:
if event.key == pygame.K_DOWN:
circleYchange = 0
circleXchange = 0
circleYchange += 0.5
if event.key == pygame.K_RIGHT:
circleYchange = 0
circleXchange = 0
circleXchange += 0.5
然后将其添加到 circleY 和 circleX,并绘制圆:
and then adding that to the circleY and circleX, and drawing the circle:
circleX += circleXchange
circleY += circleYchange
pygame.draw.circle(screen, (0, 0, 0), (circleX, circleY), size)
但它给了我这种错误:
TypeError: integer argument expected, got float
我如何减慢运动速度?
推荐答案
必须是一个具有 2 个积分组件的元组.你必须round
坐标到积分值:
The center argument of pygame.draw.circle()
has to be a tuple with 2 integral components. You have to round
the coordinate to integral values:
pygame.draw.circle(screen, (0, 0, 0), (round(circleX), round(circleY)), size)
